During an appearance on Tuesday's Watch What Happens: Live, the 33-year-old revealed to host Andy Cohen what really happened the day of her May 24 wedding that led to him jetting out of Italy and skipping the lavish event . "He sent me a long email the morning of [saying] that he was going to leave," Kanye West's wife said about her brother, who has been battling self-esteem issues over a recent 75-pound weight gain. "There was no fight." View photo . Rob Kardashian landing in Los Angeles on the day Kim married Kanye West.

I'm not even going to worry about it.' I totally understand that he wouldn't want to see a lot of people if he was feeling uncomfortable and you can only pray and wish that someone would not miss out on more memories in life, because life is about memories." Kim also answered a reader question about why she seemed to lack empathy toward her brother over this situation. "My brother and I are so close, he's one of my best friends," she insisted, noting that they are currently both living in their mother Kris Jenner's Calabasas, California, home.
